  • Patent number: 12142008
    Abstract: This document describes asymmetric camera sensor positioning for enhanced package detection. In aspects, an electronic doorbell has an image sensor that is rotated to a portrait orientation and vertically shifted relative to a lens of a camera, resulting in asymmetric positioning of the image sensor relative to the lens. The lens projects an image circle onto the image sensor and the image sensor has a sensor detection area having upper corners within the image circle and lower corners outside of the image circle to enable capture of an object located in a lower portion of the image circle and proximate to an edge of the image circle. Then, lens distortion correction is performed on a captured image to provide a final image usable to detect the package, which may be located within the image circle but outside of a conventional sensor detection area.

    Abstract: Methods and apparatus are disclosed for selecting a lens control mode for a camera in external magnetic fields or other types of non-magnetic interference. In embodiments, when the camera is activated, a test of a position sensor for the camera lens is performed by moving the camera lens through a range of positions and collecting values from the sensor. In embodiments, the sensor readings are analyzed to determine conditions such as (a) whether the sensor is saturated by an external magnetic field or non-magnetic interference, (b) whether the sensor's readings are within an error margin, and (c) whether a computed position offset for the sensor is valid. Based on the analysis, the camera is placed into a first control mode where movement of the lens is controlled using the position sensor, or a second control mode where lens movement is controlled without the position sensor.

    Abstract: An automatic calibration method for a projector-camera system including a semi-transparent screen is disclosed herein. An image sequence is caused to be captured from the semi-transparent screen and through the semi-transparent screen while a calibration pattern having features is displayed and not displayed in an alternating succession on the semi-transparent screen. A temporal correlation image is created from the image sequence and a discrete binary signal. Peaks are identified in a spatial cross correlation image generated from the temporal correlation image, where a pattern of the identified peaks corresponds to a pattern of the features in the calibration pattern. The peaks are transformed to coordinates of corrected feature points. A comparison of the corrected feature points and a ground truth set of coordinates for the features is used to determine whether the projector-camera system is calibrated.

    Abstract: A method for determining a response to misalignment of a camera monitoring a desired area includes acquiring temporal related frames from the camera including a reference frame. A pixel location is determined of a reference object from the frames. Using the pixel location of the reference object, a displacement of the camera between a current frame and the reference frame is determined. For the displacement exceeding a first threshold, a new displacement of the camera is measured by introducing at least one additional object to a camera field of view and comparing the new displacement to a second threshold. For the new displacement not exceeding the second threshold, the camera is recalibrated using a determined pixel location and a physical location of the at least one additional object. For the new displacement exceeding the second threshold, notification is provided of a misalignment to an associated user device.

  • Publication number: 20130278779
    Abstract: An automatic calibration method for a projector-camera system including a semi-transparent screen is disclosed herein. An image sequence is caused to be captured from the semi-transparent screen and through the semi-transparent screen while a calibration pattern having features is displayed and not displayed in an alternating succession on the semi-transparent screen. A temporal correlation image is created from the image sequence and a discrete binary signal. Peaks are identified in a spatial cross correlation image generated from the temporal correlation image, where a pattern of the identified peaks corresponds to a pattern of the features in the calibration pattern. The peaks are transformed to coordinates of corrected feature points. A comparison of the corrected feature points and a ground truth set of coordinates for the features is used to determine whether the projector-camera system is calibrated.

  • Publication number: 20130235213
    Abstract: An accurate camera pose is determined by pairing a first camera with a second camera in proximity to one another, and by developing a known spatial relationship between them. An image from the first camera and an image from the second camera are analyzed to determine corresponding features in both images, and a relative homography is calculated from these corresponding features. A relative parameter, such as a focal length or an extrinsic parameter is used to calculate a first camera's parameter based on a second camera's parameter and the relative homography.

    Abstract: A camera module under test is signaled to capture an image of a target. A group of pixels of the image that represent portions of several objects in the target are low pass filtered and then analyzed to compute a pixel distance between different subgroups of pixels that represent portions of the different objects. The computed pixel distance is then converted into a true distance using a predetermined math relationship that relates a pixel distance variable with a true distance variable.
